My husband went through  35 radiation  treatments and 5 chemo  for Tonsil cancer. His pets can shows cancer is gone but it's been 20 weeks since last treatment  and he is still  using the feeding  tube. He is eating  some foods but salty  foods and citrus  foods or drinks bother him. He can only  take small bites. He'd  like to find something  to fill him up so he can get rid  of  the  feeding tube. Any suggestions ?
